[gtk/wip/matthiasc/popup5: 29/128] surface: Start sketching a new surface type

[Matthias Clasen <matthiasc src gnome org>]

commit 533b038d6edd5e21a2fdc35165d828c8bed3759a

    surface: Start sketching a new surface type
    
    Start by adding a constructor. We have to call it
    gdk_surface_new_popup_full for now, since gdk_surface_new_popup
    is taken. This may be reshuffled later.
